The LED lighting test results for horticultural applications are gratifying, allowing growers to harvest raspberries in January (also called raspberries or raspberries).
The test was conducted in the Netherlands. Willemvan Eldik, a member of the Dutch research group Delphy, said the crop was sown in November, and with the mixture of red and blue LEDs, the large leaves grew "as fast as summer."
Van Eldrik said that Bud quickly grew and quickly produced nectar. The bumblebee and the bee pollinated and picked the fruit on January 31 this year.
The trial used the summer variety Tulameen (rubusidaeus) in a climate controlled greenhouse.
At the same time, the experiment of planting blackberries was carried out. Starting from November 20 last year, flower buds were grown in January this year, and pollination was carried out by bumblebees and bees, and fruits were harvested in February.
Researchers hope that the study will help Dutch growers achieve year-round production.
The potential of LEDs has caused great concern in the field of horticulture. Unlike traditional high-pressure sodium lamps, LED lighting can be dimmed according to various crops, the so-called "light formula."
Each plant requires different illumination at different times of the day and at different times of growth. Most growers currently mix 450 nm wavelength blue light (which contributes to the production of chlorophyll and beta-carotene) and 660 nm red light (which affects germination, plant growth, leaf growth and flowering).
More red light usually increases crop yield linearly. Lighting can also be dimmed, affecting the shape, taste and other characteristics of the plant.
